A share of ABC stock was worth

Find the multiplier and the percent decrease.

Create a table to help you find the multiplier.

Solve for

To find the percent decrease, divide the amount of the decrease by the starting value and convert to a percent.

Write an exponential function that models the value of the stock starting from 2005.

Use the general form of an exponential equation:

, where*m*is the multiplier found in part (a), andis the initial value.Assuming that the decline in value continues at the same rate, use your answer to (b) to predict the value in 2020.
